I have had many sets of hearing aids. Never have I had a worst pair. They were bigger than described. The wire from the hearing aid was so thick and very uncomfortable. I was not getting a good sound quality. I kept changing the domes. One got logged down in my ear and had to see my Dr. to remove it. I would never recommend these hearing aids non any on- line. Bite the bullet and buy User's recommendation: Do noy buy!!. Bite the bullet and do not order any on-line. You get what you pay for !!
